چکیده
This paper presents a new approach for PLL for synchronization with the public grid phase and frequency of grid-connected single phase inverter. The approach uses trigonometric transformations of the inverter output voltage and the grid voltage. The proposed mathematical model is then studied by means of computer simulation for different voltage amplitudes of the grid voltage as well as the inverter output voltage. Keywords–grid-connected inverter, PLL, trigonometric transformations

متن کاملThe Design of a New Double Loop Controller For Simultaneous Adjustment of Input and Output Voltages of Single-Phase Grid-Connected Inverter
Although LCL filters are used widely in the grid connected inverters to reduce high-orderharmonics, such a system increases system order and therefore sustainable design of closed-loopcontroller system will be complicated. Recently, the single-loop control strategy has beensuggested for L or LC filter based grid-connected inverters. However, the use of single-loopcontrol directly in LCL filter-...

Because of installation for local consumers and since it is free of all contaminations, connecting photovoltaic cells to the grid via single-phase inverter is significantly on the rise. In this paper, a new simple current control is proposed for a single-phase grid-connected voltage source inverter. Using the PQ theory and modelling a single-phase system as an unbalanced three-phase system, a m...
متن کاملAn LCL-filtered Single-phase Multilevel Inverter for Grid Integration of PV Systems
Integration of the PV into the electrical grid needs power electronic interface. This power electronic interface should have some key features and should come up with grid codes. One of the important criteria is the quality and harmonic contents of the current being injected to the grid. High-order harmonics of the grid current should be very limited (lower than 0.3% of the fundamental current)...
